From Idea, Sketch, or Sample Part to 3D Model

3D modeling is the process of creating a digital representation of a physical object. A well-built CAD model can be used for 3D printing, prototyping, product development, reverse engineering, repair parts, manufacturing review, and presentation.

Whether you already have a drawing or only have an idea, our team can help develop the model and prepare it for the next step.

Our CAD Design Process

01

Send Your Idea

Send a sketch, drawing, CAD file, photo, or physical sample.

02

Review Requirements

We review size, function, material, tolerance, and intended use.

03

Create the Model

Our team builds or modifies the 3D model based on your needs.

04

Prepare for Next Step

The model can be used for 3D printing, prototyping, review, or production.

Design Files We Can Work With

You do not need to have everything ready. Send what you have and we can help determine what is needed to move forward.

CAD

Existing CAD Files

We can review and modify existing 3D files for printability and design updates.

STEP · STL · OBJ · 3MF
SKETCH

Drawings & Sketches

Start from a hand sketch, technical drawing, or dimensioned concept.

PDF · JPG · PNG · Drawing
PART

Physical Samples

Bring or send a sample part for measurement, redesign, or reverse engineering.

Sample · Broken Part · Old Part
SCAN

3D Scan Data

Use scan data as a reference for reverse engineering or shape reconstruction.

Mesh · Point Cloud · Reference Geometry
PRINT

3D Printing Output

Models can be prepared for prototyping and manufacturing after design review.

FDM · SLA · SLS · MJF

CAD Design and 3D Printing Are Connected

A model that looks good on screen may not always be ready to print or manufacture. We can help review wall thickness, tolerances, support requirements, part orientation, material selection, and design limitations before production.
